Information from the backend is available through the XML status server 
on 'http://mybackend:6544/xml'.  Contained are the status of all 
recorders, The upcoming schedule, jobs in the queue, recording disk 
stats, load averages, basic guide data information.  If you check out 
'MythXMLTest' in contrib, you'll find a number of additional pages with 
other accessible information.  Alternatively, you can access the backend 
directly through mythprotocol on port 6543.

Information from the frontend will only be available from the telnet socket.

The perl and python bindings provide access to these interfaces to 
varying degrees. Below is an example of retrieving some of that 
information through the python bindings (in trunk).

 >>> from MythTV import MythBE, MythDB
 >>> be = MythBE()

get total recording count
 >>> len(be.getRecordings())
141

get upcoming recording count
 >>> len(be.getScheduledRecordings())
44

get total and free recorder counts
 >>> len(be.getRecorderList())
11
 >>> len(be.getFreeRecorderList())
10

get information on current recording
 >>> be.getCurrentRecording(7)
<Program 'XXI Winter Olympics','2010-02-18 01:30:00' at 0x803c3d1d0>
 >>> be.getCurrentRecording(7).title
u'XXI Winter Olympics'
 >>> be.getCurrentRecording(7).subtitle
u'Snowboarding, Speed Skating, Skiing'

get frontend information while moving around the menus
 >>> db = MythDB()
 >>> fe = db.getFrontend('mythbe')
 >>> fe.sendQuery('location')
'Playback LiveTV 00:01:23 of 00:01:44 1x 4642 2010-02-18T01:30:00 2493

 >>> fe.sendQuery('location')
'mainmenu'
 >>> fe.sendQuery('location')
'playbackbox'
 >>> fe.sendQuery('location')
